To @ZZ whom, it may concern:

Be it known that I, FRED P. GORIN, a citizen of the United States,residing at Chicago, in the county of Cook and State of Illinois,haveinvented a new and useful Attachment for Type-Writers and SimilarMachines, of which the following is a specification.

This invention relates to an attachment for type-writers and similarmachines and belongs to the class of attachments adapted to produce aplurality of copies and now usually designated as multigraphs.

The object of the invention is to provide an attachment capable ofmaking a single copy, two copies, ora number of copies in a simple andefficient manner and to readily change the attachment to adapt it tomake single or multiple copies without loss of time. The most commonform of making duplicate copies is by the use of carbon-paper; but suchpaper is expensive, perishable, and occasions much loss of time inmanipulating it to place it between the sheets to be printed upon and toremove it from the sheets after they have been printed upon and inintroducing the sheets into the machine by a distinctly-separateoperation. By later improvements it has been attempted to produceduplications of printed work in type-writers without the use ofcarbon-paper; but it has been found difficult to adapt such attachmentsto make single copies, as Well as duplicates, with facility anddespatch. The present invention is intended to obviate the 'difficultiesheretofore experienced by the use of carbon-paper and also with themultigraphs just referred to.

The invention embodies certain principles which may be carried out inthe construction hereinafter described and will be more particularlypointed out in the subjoined claims.

Like reference-letters refer to corresponding parts in the severalfigures of the drawings, in which- Figure 1 is a front elevation of thecarriage of a type-writer in its lifted position to which the attachmentis applied.

Fig. lO is a detail cross-section on the line 10 lO, Fig.1 of the drawings. Fig. l2 is a top View of the same. Fig. l1 is adetail section on the line l1 11, Fig. l of the drawings. Fig. 18 is atop View of the same. Fig. 14 is a vertical section in detail of one ofthe reels for the supplemental ribbon and the mechanism for securing thesame to the shaft.

The attachment is in the drawings shown appliedl to a Remingtontype-writer, although it is obvious it may be equally Well applied toother makes of machines. Inasmuch as the attachment is applied to thecarriage of the Remington type-writer, it is not necessary to show thedetails of the lower part of such machine, but which lower part ofcourse is provided with the usual set of keys, operating-levers, typeand ribbon, or other inking device. The lower part of this typewritingmachine is in the drawings designated by the letter A. A carriage isconnected to slide upon a bar of the lower part of the machine in theusual manner and is provided with the customary features ofconstruction,

which are well known and need not therefore be specially described. Thiscarriage is designated in the drawings by the letter B and is pivoted soas to swing down into operative position or up into position forinspection, as is usual in such cases. It will not be necessary tospecifically define the construction of parts of this carriage, as theyare well known to persons skilled in the art, and therefore it is to beunderstood that such parts of the carriage as are not specificallyreferred to in this 10o specification are of the usual construction andthat when it is advisable to describe any particular part which is wellknown in its connection with features of the attachment a separatereference-letter will be applied to such part. In connection with thiscarriage there is used the ordinary printing platen or roll, (designatedB,) and arranged in a holder, the construction of which will behereinafter described, there is a supplemental inking-ribbon C. When buta single copy is desired, this supplemental inking-ribbon C is thrownout of the way and not used, the single copy being made by the use ofthe main ribbon A on the lower part of the machine or any otherconvenient location where it may be placed. When two or more copies aredesired, the supplemental ribbonv is employed and is placed between thesheets of paperin a manner which will be hereinafter described. By wayof description of the use of ribbons in connection with one or morecopies it may be said that to make one copy the type-bars are used inconnection with the main ribbon of the machine, as just suggested, andwhen two copies are desired an additional or supplemental ribbonisplaced between the two sheets of paper, and the type acting through thefirst sheet and through the supplemental ribbon makes the impression onthe second sheet, it being understood, of course, that the raisedsurface of the type makes a corresponding impression in the first sheetand the supplemental ribbon and thereby is enabled to leave a similarmark upon the second sheet, with which the raised portion of the ribboncontacts by reason of the pressure of the type. However, in thisoperation not only will these two impressions be made, one on eachsheet, but there will also be a third impression on the back of thefirst sheet, which is not only of no use, because it is a reversedimpression, but mars the appearance of such first sheet, .and to avoidthis defect provision is made for placing a lremovable protecting-stripC of tape, paper, or other material between the supplemental ribbon andthe first sheet,which tape will thereby receive the impression andprevent the mutilation of such sheet. If three copies are desired,provision is made for placing a third sheet of paper (preferably thinnerthan the other two sheets and in lieu of the protecting-strip justmentioned) between the supplemental ribbon and the irst sheet, wherebythis third sheet will receive an impression upon itsback of a reversedcharacter, but which may be read correctly when-looking from the frontor other side of such thin sheet. It is obvious that this snpplementalribbon may be of any convenient .size and shape, according to theoccasion or machine on which they are employed, and may be clamped orheld in many different ways. An advantageous and efficient mechanism forclamping the supplemental ribbon vand. removable protecting-strip isshown in the accompanying drawings, and consists in hinged plates, moreparticularly illustrated in Figs. 8 and 9of the drawings. The holderpreferred employs three plates for two or three copies, each separablefrom the other and normally held together by acoiled spring wound uponthe pintle or pivot of the hinge andbearing upon the bottom plate. Oneof these plates, and preferably the top plate,

` may be for convenience termed the fixed plate and the other two platesthe hinged plates-that is, the fixed plate has the lugs forming thebearings for the pivot of the other two plates. The fixed plate is inthe drawings designated by the letter D, the intermediate plate by theletter' D', and the bottom plate by the letter D2. The protecting-stripC should be capable of being readily removed, and one device for thepurpose which has been found advantageous and efficient is t-he holdercomposed of plates just referred to. The protecting-strip when appliedto this holder extends approximately the length of the width of thepaper to be written upon and has its ends clamped by the plates of theholder by inserting such ends between the lower and the intermediateplate. It is obvious that with this construction the protecting-stripmay be readily removed by separating the plates between which its endsare clamped. The intermediate plate serves as a horizontal guide for theribbon in that it is provided with overturned edges a, extendinghorizontally toward the center of the plate and leaving a slit oraperture a',

4.through which the edge of the ribbon may be inserted and drawn untilit is practically inclosed between the main plate D and its overturnededges, there being thus formed a horizon tal guideway for the ribbon.The top plate may have an extension at its end to change the directionof travel of the ribbon, and a convenient construction for this purposeis shown in Fig. 8 of the drawings, in which there is a transverseelongated slot about the width of the ribbon, (lettered 1),) throughwhich the ribbon may pass through the plate, and a sloping edge cut atan angle of about forty-tive degrees, over which such ribbon may beturned a quarter-turn and which is designated bythe letter c, and astraight edge at its rear side, which may be provided with a roller d,as shown, whereby the ribbonis given the proper direction of travel toadapt it to wind upon a reel E, as shown in Figs. l, 2, and 3 of thedrawings. Any suitable tension device may be employed to give the ribbonthe proper tension, and in the drawings there is shown for this purposea spring-actuated brake e, which brake is fastened to the carriage ofthe machine and bears at its free end upon one iiange of the drum. Inthe plate D there may be also fastened the ends of wires F, which wiresextend transversely of the machine at a distance apart slightly inexcess of the width of the supplemental ribbon and between which thefree IIO portioirof the ribbon-thatis, the portion ex- A tending overthe platen or roller and upon which the type act-is guided and held.This holding of the ribbon by these wires is effected because the wiresare taut and comparatively rigid, while the ribbon with the utmosttension placed upon it is not so rigid, and consequently the edges ofthe ribbon, being slightly out of the same horizontal plane at differentpoints, catch against the wires, and it is thereby held in place againstthe feeding action of the paper when the latter is being moved. It is tobe .noted at this point that these detaining-wires are an accessory oraddition which while advantageous are not necessarily employed. It' thissupplemental ribbon is given sufficient tension by any proper device forthe purpose, the paper being fed will be unable to overcome suchtension, and in such case the detaining-wires will not be necessary; butwhen sufficient tension for this purpose is given to the ribbon it willrequire considerable force to feed such ribbon and overcome the tensionfor the time being, and it is therefore desirable to decrease thetension and thereby decrease the friction to be overcome in operatingthe feeding device, and to this end the detainingwires are employed andfound advantageous.

It will of course be understood that these ribbon-holders for thesupplemental ribbon are used in pairs-that is, there is one at each sideof the platen, with the ribbon stretched between them and passingthrough them. This is clearly shown in Figs. l and 3 of the drawings.

During the operation of the machine the supplemental ribbon is of courseplaced in the typeline-that is, in the line upon which all the type willstrike-and is arranged very close to the platen or roller, whichreceives the ultimate impact of the type. Vhile the attachment may beoperated with the supplemental ribbon always in this position, yet theproximity of such ribbon to the platen will make it difficult to placesuch ribbon between the incoming sheets of paper, and for that reason itis preferred to provide a mechanism adapted to move the ribbon out fromthe platen, so as to provide more space between such ribbon and platen,and thus enable a sheet of paper to be more readily inserted between theribbon and the platen. It is manifest that many different forms ofmechanism may be employed to embody this principle, and I do nottherefore wish to be understood as limiting myself to the mechanismshown and hereinafter described for the purpose; but a convenient andeffective device to accomplish this object is illustrated in thedrawings as consisting of pivoted arms hung from a center eccentric tothe center of the platen in case a circular roll or cylinder is used forthe platen. These arms are particularly well shown in Figs. 3, et, 5,and 6 of the drawings and designated by the letter Gr and may beconveniently pivoted, as shown in Fig. 3 of the drawings, upon thesleeve H, Y

surrounding the shaft I, on the ends of which shaft are mounted thereels or drums E, before referred to. It is evident that when these armsG are swung either backward or forward they will carry the holders(which are secured at the free ends thereof) and the ribbon which passesthrough the holders outward from the platen, so as to leave more spacebetween the platen and the ribbon.

When the sheets of paper are first fed into the machine and their upperedges clear the lower scale B3 on the carriage, such edges of the paperwill be so close to the type-line that it will be difficult to separatethem in order to pass the sheets of paper above and below the ribbon,respectively, and it is desirable to facilitate the introduction of thepaper into its proper position that a greater length of the sheets shallbe made to protrude beyond the edge of the lower scale than that portionextending between such scale and the type-V line, and the only way toeffect this end is to move the supplemental ribbon and lower scale withrelation to each other. The lower scale and supporting parts may bemoved with reference to the type-line, the ribbon above the same, or thesupplemental ribbon may be moved, and in practice it has thus far beenfound most convenient and easier to move the supplemental ribbon awayfrom the typeline and the lower scale than to move such scale from theribbon, although it is to be distinctly understood that the invention isnot to be limited to the movement of the ribbon, although that is thepreferred arrangement. It is advantageous to move the ribbon for anotherreason once before alluded to in this specification, and that is becausewhen but a single copy is desired the supplemental ribbon is not to beemployed and should of course be moved out of the way. The supplementalribbon passes through the holders at each end, as before described, andthe holders being mounted upon the pivoted arms, which latter swingeccentrically to the axis of the cylindrical platen, it follows that theone mechanism or device-viz., the pivoted arms-performs the twoindependent functions of lifting the supplemental ribbon outward fromthe platen and moving such ribbon away from the type-line. These twoprinciples are, as above suggested, entirely independent. and may beseparate] y employed without departing from the spirit of the invention;but it is advantageous to combine them in the operation of the machine,and

the pivoted arms just referred to provide a panying drawings and willnow be described. A plate (designated by the letter K) is suitablysecured to the frame of the carriage, and preferably in a detachablemanner, by means of screws n2, as shown in Fig. 7 of the drawings. Thisplate K projects in the same direction as the pivoted arm at thecorrespondingend of the machine and has its lower end arranged justabove the plate or clamp of the holder secured tosuch arm when the partsare in the position shown in Fig. 4L of the drawings. This lower edge iscurved or segmental in shape and provided with a series of notchesformed therein. There are preferably three notches, (designated,respectively, by the reference-letters m, m', and m2.) Pivoted to an armG is a lever L, at one end of which may be a thumb-piece and at theother end of which is a dog n, adapted to engage either of the notches mfm" m2. A spring o bears upon the end of the lever L nearest the dog andtends to engage the dog of the lever with a notch. The dog may bereleased from any particular notch by pressing upon the thumbpiece atthe other end of the lever, and thus lifting the dog out of the notch.Inasmuch as the lever is mounted on the pivoted arm carrying thesupplemental ribbon, it swings with the pivoted arm, and as the arm andribbon are moved to the intermediate position over the type-line the dogengages the intermediate notch m and holds the ribbon securely in thatposition, or as the pivoted arm and ribbon are moved away from thetype-line toward the notch on2 the dog when it reaches the latter willsecure the parts in` that position, and thus hold the ribbon lifted fromthe platen and rearward of the typeline, whereby the sheets of paper maybe readily introduced over such ribbon, and when it is desired to makeonly a single copy, and therefore the attachment should be thrown out ofoperative position, the dog is released and held out of engagement withthe notches and the pivoted lever and ribbon thrown forward until thedog is opposite the `notch m, when it will enter the same and maintainthe attachment out of operative position.

As the sheets of paper upon which the imprint is desired to be made arefed into the Vmachine it is desirable to temporarily lift out of the waythe paperguides and frictional clamping or feed rolls, so that the upperedges of the sheets of paper may be separated sufficiently to allow thesupplemental ribbon to pass between them. In the usual form oftype-writer the paper-guides are independent of the frictionalclamping-rolls, a slot being out through the upper part of suchpaper-guides to admit of the passage therethrough of the lower surfaceof the frictional clamping or feed rolls. Moreover, in such usualform oftype-writer there are three sets of paper-guides and frictional clampingor feed rolls, and each set is independent of the other. In the presentattachment it has been found ing or feed roll to its paper-guide, sothat these two parts will move together. In the drawings the endpaper-guides are designated by the letters M M and the centralpaperguide by the letter N. Likewise the end frictional clamping or feedrolls are designated by thezletters O O and the central roll by thelet-ter P. A convenient construction for the end paper-guides and rollsis to hinge such paper-guides to brackets Ml M2, which are in turnclamped to the carriage, and to mount the rolls in the brackets,providing, of course, apertures in thepaper-guides, through which thesurfaces of the rolls may project and contact with the platen in theusual manner. By this construction the frictional clamping or feed rollsare carried by the paper-guides, so that such guides and rolls may movetogether when it is desired to lift them from the platen for the purposeof facilitating the entrance of the sheets of paper. A similarconstruction may be made at the center; but at that point it has beenfound more convenient to hinge the paper-guide to the front bar of thecarriage and form bearings in such guide for the shaft of the roller,just as is done in the ordinary construction. In the figures of thedrawings and more especially in the detail views, Figs. 11 and 13, thecentral paper-guide N is shown as hinged to the IOO bracket, whichlatter is clamped by the clamps i N N2 to the front bar B of thecarriage. Inasmuch as all these paper-guides and rollers should be movedout of the way to permit the sheets of paper to be spread apart at theirupper edges, it is of course desirable to save time by moving them alltogether, and to this end the shafts of all the frictional clamping orfeed rolls are extended, as shown in Fig. 1 of the drawings, and arock-lever Q is provided at its two ends with slotted arms r, bent atright angles to the same, adapted to engage the ends of the shafts ofthe end rolls, and with projecting pins s, adapted to project under theextended shaft of the central roller P. This rock-lever may have ahandle t, by means of which it may be manipulated, and when this handleis lifted the lever is rocked and all the paper-guides and rollers aresimultaneously lifted above the surface of the platen,so as to permitthe ends of the sheets of paper to be spread apart. When the paper hasbeen properly introduced and is in position to be written upon, therollers and paper-guides may be depressed; but the construction of theattachment is such that the central paper-guide and roller are notnecessarily depressed simultaneously with the end guides and rollers,because the pins 's only bear upon the under side of the eX- IIO IZO

this is to prevent too much friction being applied to paper which doesnot require the action of a central guide and roller. In case envelopsare desired to be printed upon it is advisable to use the centralguideand roller, as well as the end guides and rollers. As a convenientmeans of feeding the supplemental ribbon the construction illustrated inFig. of the drawings has been devised. In this construction a transverseshaft I is supported in the frame of the carriage and has looselymounted upon each end thereof a drum EI upon which the supplementalribbon is to be wound. end is a :ratchet T. The cylindrical platen has,as is usual, at one end a ratchet XV, which is engaged by a pawl U,operated by a pivoted elbow-lever X. Projecting from the` upper end ofthis elbow-lever is a journal Y, upon the inner end of which the pawl Uis pivoted and upon the outer end of which a pawl V maybe pivoted. TWhenthe rock-lever X is moved, it will operate both pawls and cause thecylindrical platen to be moved one step and the reel E, to which theratchet T is secured, as hereinafter provided, onestep, and thus windthe ribbon upon such reel.

The construction for clutching and unclutching the reels to the shaft is(shown in Figs. 3 and I4 of the drawings, andspecially clearly in thislast-mentioned figure. The ratchet T is secured by a pin to the shaft,so as to rotate with it, and has formed longitudinally of its axis ahole f, adapted to receive a bolt Z, which latter is springacted andsupported in the reel E. This bolt Z passes through the reel and mayenteran aperture f. When the bolt thus enters the hole f in the ratchet,it will lock the ratchet to the reel or drum and cause the two to besecured together and revolve together, and thus feed the ribbon at thatside, as before suggested. At length, the ribbon being fed as far as itwill go in that direction, it may be desirable to reverse the directionof feed, and to this end a corresponding drum E is loosely mounted uponthe shaft I at its opposite end and may be secured to the same s/o as tomove with it by locking a washer TXkeyed to the shaft at that end, tothe drum by means of the bolt Z at such end, povided, of course, thebolt at the ratchet end of the machine is withdrawn and locked out ofengagement With the hole in the ratchet, which may be done by turning itso that a shoulder upon it will engage a stud g on the reel.

From the abovedescribed construction it will of course be understoodthat in the normal operation of the attachment one reel is loose uponits shaft and the other secured to the shaft and that if, for instance,the reel at the right side of the machine is rotated by the pawl whichengages its ratchet T from left to right the reel at the left side ofthe machine will revolve loosely on the same shaft from right to leftbecause of the drawing act-ion of the ribbon, which is being at Securedto this shaft at one,

the time wound upon the reel at the right side of the machine. On theother hand, if the bolt Z is withdrawn from the ratchet T and secured ininoperative position and the bolt at the left side of the machine isinserted in the .aperture in the washer T then the action of the pawl incausing the ratchet T to rotate will also cause the reel at the left ofthe machine, which is locked to its shaft, to rotate from left to right,so as to wind the ribbon at that end, and this winding of the ribbon atthat end will draw upon the reel at the right side of the machine andcause it to revolve in the opposite direction, and consequently pay outthe ribbon. In this manner the supplemental ribbon is fed from one sideof the machine to the other and then back again by merely reversing theclutching or locking mechanisni-that is, by locking at one end andunlocking at the other.

Itis clear that the mechanism just described for feeding thesupplemental ribbon is not essential, but is merely a simple andadvantageous mechanism and the best which I at this time know for thepurpose. Persons versed iu this line of machinery will readilyappreciate equivalent mechanisms for performing the same function,which, while differing in form, will embody the same spirit, and Itherefore do not wish to be understood as limiting myself to theconstruction described.

Referring now particularly to Figs. 1, 7, and 8 of the drawings,attention is directed to the automatic lifter for the supplementalribbon. The holder for the ribbon is composed, as before stated, ofseveral plates, some of which are hinged so as to be moved away from t eother or additional plate. This hinge eature is desirable, not only, asabove described,to enable the plates to be separated, so that the ribbonmay be readily inserted and so that a piece of tape may be inserted, asabove described, but also for the purpose of automatically lifting theribbon farther away from the platen and for lifting the wires and ribbonover the lower scale of the carriage when they are being changed fromtheir inoperative position to a position in which they are capable ofperforming their usual functions in the attachment. The pivot or axisupon which the plates D and D2 turn has secured to it a lever G',provided with a toe or projection thereon. This toe passes through aslot in the stationary plate D and bears upon the plate D'. A stud orpin H projects inwardly from an end bar of the frame of the carriage inthe path of the upper end of this lever G. As the holder is rockedforward to lift it, with its ribbon, above the cylindrical platen andcarry it away from the type-line the upper end of this lever G' strikesthe pin or stud H and rocks the same upon its axis and causes the toethereof to press against the hinged plate D and lift the latten, withits ribbon and wires, so that said wires will clear the lower scale andsaid ribbon be fur- IOC IIO

ther removed from the platen than the eccenprovided with a lever andtoe, as just described, and a stud or: pin is correspondingly arrangedat each side of the machine to engage such lever, so that simultaneouslythe hinged plate D of each holder will be lifted,

as specified. Fig. 7 of the drawings shows in detail the holder, whichis arranged at the left side of the machine, provided with its lever andtoe and in dotted lines shows the position assumed by the parts afterthe ribbon and wires have been automatically lifted by the engagement ofthe lever against the pin. Fig. 9% shows the holder at the opposite endof the machine, with the parts drawn upon a somewhat-larger scale andthe lever in position to engage the pin, and also a crosssection of themain ribbon which is employed in the machine.
